İ., Bilğiç Alkaya D., Ayaz Seyhan S., Cesur S., Gündüz O.uberculosis is a disease caused by a bacillus called mycobacterium tuberculosis which can be seen in other organs, especially in the lungs. Tuberculosis is an infectious, infectious, inflammatory, acute or chronic-trending bacterial infection. Since the treatment is insufficient with a single drug and the bacilli are resistant to this antibiotic, various antituberculosis drugs are used side by side during the treatment. Side-by-side use of the drugs breaks the resistance of the bacteria but creates a lot of side effects for the patient. We aim to reduce the existing side effects by loading the active agents of rifampicin, isoniazid, pyrazinamide and ethambutol, which are used as antituberculosis drugs, to a biodegradable nanofib. Primarily, PCL polymer material was dissolved in DMF: THF (v / v). After preparing PCL solution in 3%, 6%, 9%, 12% and 15% concentrations, optimization studies were performed by using electrospin device at various voltages. The SEM images of the obtained PCL fibers were examined and drug loading was performed at the suitable PCL concentration. In the planned study, FTIR images of the fibers loaded with the drug will be examined and controlled drug oscillations will be provided at the stomach and intestinal pH as an in vitro trial and spectrophotometric measurements will be taken. The release of drugs loaded into nanofibers are slower due to the wide surface area of the nanofibers, which offers a more controlled drug release.Publication Metadata only Preparation and characterization of silver-doped hydroxyapatite from seashell by different methods(2018-09-08) AYAZ SEYHAN, SERAP; BİLĞİÇ ALKAYA, DİLEK; CESUR, SÜMEYYE; OKTAR, FAİK NÜZHET; GÜNDÜZ, OĞUZHAN; , Ayaz Seyhan S., Bilğiç Alkaya D., Öztürk B.

N., GÜNDÜZ O.The marine species are specially used for the fabrication of bioceramic nano-powders with natural methods for their use in controlled drug delivery. However, there are only very limited studies regarding the production and synthesis of hydroxyapatite (HA)-based drug delivery systems from marine structures. In this study, poly (vinyl alcohol) (PVA) containing Rifampicin (RIF)-loaded Orange Spiny Oyster Seashell (Spondylus barbatus) hydroxyapatite (HA) composite is synthesized by an in situ ultrasound-assisted method. All samples were analyzed by X-ray diffraction (XRD), Fourier transforms infrared (FTIR) spectroscopy, and Scanning electron microscope (SEM), respectively. The in vitro drug release tests of the obtained samples were performed in a phosphate-buffered medium (PBS) at 37 degrees C. Drug release was evaluated according to five varying kinetic models. In vitro RIF release from HA/PVA composite in phosphate buffer (pH 7.4) showed prolonged sustained drug release. From the drug release kinetic models, Higuchi and Korsmeyer-Peppas were found to be the best model for the three ratios based on the correlation coefficient. The diffusion component is less than 0.5, which indicates quasi-fickian diffusion. From the kinetic study results, the RIF-loaded marine phase composite has potential use in drug delivery applications as it shows positive sustained drug release behavior.
